Which of the following statements about members of the family enterobacteriaceae is not true? it includes many medically relevant bacteria. members only reside in the intestinal tract of humans. it includes e. coli, enterobacter, salmonella, and shigella. members are facultative anaerobes. all of the choices are correct.

The correct answer will be option- All of the choices are correct.

Explanation:

Enterobacteriaceae are a group of bacteria belonging to a large family.

The group includes gram-negative and non-spore forming bacteria mainly like E. coli, Salmonella, Shigella, Enterobacter and Yersinia pestis. The main habitat of these bacteria is the lower gastrointestinal tract of various animals, the reason they are also known as 'enterics".

They are facultative anaerobes and feed on the carbohydrates like sugar and nitrates present in the tract. They ferment the sugars and reduce the nitrates to nitrites. many strains and species of these bacteria are used in the clinical department.

Thus, option- All of the choices are correct is the correct answer.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
